Try 3 because 3 times 3 is. 9
Answer:
Step-by-step explanation:
So we have the function:
To find the inverse of a function, switch f(x) and x, change f(x) to f⁻¹(x), and solve for f⁻¹(x). So:
Add 11 to both sides:
Divide both sides by 6:
Take the fifth root of each side:
And we're done :)
Add the numbers and divide by 5 to get a mean of 6.4
8 - 6.4 = 1.6
4 - 6.4 = -2.4
7 - 6.4 = 0.6
8 - 6.4 = 1.6
5 - 6.4 = -1.4
Add the absolute value of each: 1.6 + 2.4 + 0.6 + 1.6 + 1.4 = 7.6
Divide by 5 = 1.52
1.5
Answer:
n = 3 + i√11 , 3 - i√11
Step-by-step explanation:
This is a quadratic equation and the first step is to write it in standard form:
5n^2 - 30n + 100 = 0
Divide through by 5:
n^2 - 6n + 20 = 0
Completing the square:-
(n - 3)^2 - 9 + 20 = 0
(n - 3)^2 = -11
n - 3 = i√11 or - i√11
n = 3 + i√11 , 3 - i√11
(2 complex roots).
